PHP結合Memcached

    上一篇文章給大家介紹了memcached的安裝以及簡單的命令。這裏給大家介紹php如何結合memcached。配置其實很簡單的就幾步操作。

1. 先安裝php的memcache擴展，相信大家對php的擴展模塊安裝不會陌生。

首先可以去pecl.php.net    官網下載安裝包，我這裏下載的2.2.5版本
# tar zxfmemcache-2.2.5.tgz 
# cd memcache-2.2.5
# /usr/local/php/bin/phpize
# ./configure --with-php-config=/usr/local/php/bin/php-config
# make && make installl安裝完後會有類似這樣的提示：
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20130626/

然後修改php.ini，把extension_dir = "./" 修改爲
extension_dir = "/usr/local/php/extensions"並添加一行
extension="memcache.so"

然後創建目錄 mkdir /usr/local/php/extensions

將no-debug-non-zts-20130626/目錄下的memcache.so移到/usr/local/php/extensions/目錄下

/usr/local/php/bin/php -m |grepmemcache 可以檢驗擴展模塊是否添加成功。

2. php腳本測試

首先寫一個測試的php腳本

vim test.php 

#############

<?php

$mem = new Memcache;

$mem->connect("localhost", 11211);

//保存數據

$mem->set('key1', 'This is first value', 0, 60);

$val = $mem->get('key1');

echo "Get key1 value: " . $val ."<br>";

//替換數據

$mem->replace('key1', 'This is replace value', 0, 60);

$val = $mem->get('key1');

echo "Get key1 value: " . $val . "<br>";

//保存數組數據

$arr = array('aaa', 'bbb', 'ccc', 'ddd');

$mem->set('key2', $arr, 0, 60);

$val2 = $mem->get('key2');

echo "Get key2 value: ";

print_r($val2);

echo "<br>";

//刪除數據

$mem->delete('key1');

$val = $mem->get('key1');

echo "Get key1 value: " . $val . "<br>";

//清除所有數據

$mem->flush();

$val2 = $mem->get('key2');

echo "Get key2 value: ";

print_r($val2);

echo "<br>";

//關閉連接

$mem->close();

?>

然後執行命令：/usr/local/php/bin/php test.php
看看能否得到如下內容：

Get key1 value: This is first value<br>Get key1 value: This is replace value<br>Get key2 value: Array

(

    [0] => aaa

    [1] => bbb

    [2] => ccc

    [3] => ddd

)

<br>Get key1 value: <br>Get key2 value: <br>

如果得到此內容說明結合成功。
